4-amino-3-hydrazino-5-mercapto-1,2,4-triazole (Purpald®)'un Elektropolimerizayonu

Abstract

In this study electropolymerization of 4-amino-3-hydrazino-5-mercapto-1,2,4-triazole (Purpald ® ) on the disposable pencil graphite electrode (PGE) was described and the electroactivity of the polymer film coated and naked PG electrodes were checked against K 3 [Fe(CN) 6 ] / K 4 [Fe(CN) 6 ] in pH 8 Britton‑Robinson (BR) buffer solution. The electropolymerization of Purpald ® film was performed with cyclic voltammetry (CV). The optimal conditions of Purpald ® film coated electrode were performed using electrochemical impedance spectroscopy (EIS). The conductivity of the Purplad ® modified electrodes was compared with bare and p-phenylenediamine modified PG electrodes by EIS technique. The results indicated that electrosynthesized poly(Purplad ® ) film could be used for modification of electrodes to be used in electrochemical analysis and sensor applications.
